Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, the utility model includes the first air door 1 and the second air door 2 positioned at underground, the He of the first air door 1
The four railing mechanisms 7 for switching air door are provided with second air door 2, the outside and inner side of the first air door 1 are respectively arranged with
First photoelectric sensor group 3 and the second photoelectric sensor group 4, the inner side and outer side of the second air door 2 are respectively arranged with the 3rd photoelectricity
The photoelectric sensor group 6 of sensor group 5 and the 4th, the first photoelectric sensor group 3, the second photoelectric sensor group 4, the 3rd photoelectric sensing
The photoelectric sensor group 6 of device group 5 and the 4th is all connected with PLC 8, and PLC 8 controls two four by solenoid directional control valve 9
Linkage 7, PLC 8 are used to gather the first photoelectric sensor group 3, the second photoelectric sensor group 4, the 3rd photoelectric sensing
The information of the photoelectric sensor group 6 of device group 5 and the 4th, and solenoid directional control valve 9 is controlled, solenoid directional control valve 9 is connected with fuel tank 10 and liquid
Limit switch 14 is provided with potential source 11, the first air door 1 and the second air door 2, is provided with quadric chain 7 and is opened for monitoring
Open the limit switch of position.
Preferably, the first photoelectric sensor group 3, the second photoelectric sensor group 4, the 3rd photoelectric sensor group 5 and the 4th light
Electric transducer group 6 includes the photophore 12 being arranged in side wall, and is arranged on corresponding with photophore 12 on another side
Light receiving device 13.
Preferably, hydraulic power source 11 uses YHG1G100/56 × 300LJ-HL1WT1 type hydraulic cylinders, the model of PLC
For FX0n-24MR-001, the solenoid directional control valve 9 changes the solenoid directional control valve of valve series using WE6 type electromagnetism
4WE6H50AWG24N。
The course of work of the present apparatus is as follows：
When having staff or equipment reaches the first air door 1, the first photoelectric sensing group 3, and now the second wind are blocked
Door 2 is closed.Limit switch 14 and four photoelectric sensor groups input a signal into PLC FX0n-24MR-001
Processing, the output signal of PLC 8, driving WE6 solenoid directional control valves 9 act, and hydraulic oil is entered Driven by Hydraulic Cylinder hydraulic cylinder
YHG1G100/56 × 300LJ-HL1WT1 realizes the unlatching of the first air door 1.First man block the first photoelectric sensor group 3 it
Afterwards, other photoelectric sensor groups are unable to input signal, and PLC FX0n-24MR-001 enters line delay 5 seconds, light first in 5 seconds
Electric transducer group 3 is blocked every time all can reclocking.During this period, door can be constantly in opening, to the last one
People is by the way that after being delayed 5 seconds, PLC FX0n-24MR-001 sends signal, and WE6 solenoid directional control valves 9 commutate, hydraulic cylinder
YHG1G100/56 × 300LJ-HL1WT1 is stretched out, and the first air door 1 is closed.Whole control program all uses PLC sequential organization
